Compatibility

Browserslist​

In an ESBoot project, browser compatibility is configured with the browserslist field in package.json.

{
  "browserslist": {
    "development": ["last 1 chrome version"],
    "production": ["Chrome >= 67"]
  }
}

For Multi Platforms mode, you can define different production targets per platform, such as:

  • pc-native-production
  • pc-browser-production
  • mobile-native-production
  • mobile-browser-production

See the official browserslist docs for all supported queries.

Packages Inside node_modules​

Normally, packages in node_modules are excluded from compilation. If a modern package ships syntax that is too new for your target, you can force it through Babel using extraBabelIncludes.

Notes
  1. Compiling extra packages from node_modules will slow down builds.
  2. This only works in the webpack bundler because other bundlers do not use Babel in the same way.
